Oil cooler question
I just did an EGR delete, new PMM Lifetime Oil Cooler, complete flush, and coolant filter (among other updates) on my dad's early 04. The old oil cooler was so plugged that you couldn't blow air through it, and the EGR cooler blew out (lots of white smoke). The deltas on the ECT/EOT are starting to climb back up again. After I first got it running again, the deltas were running around 5 degrees, the other day they were up around 15-20. ECT was 188-192 and EOT was 205-212. Has anyone else used the PMM cooler, and what are your deltas running? I'm afraid this thing's plugging up again, even with the flush and coolant filter. Any thoughts?

Flushed after. I didn't have much choice. The egr cooler was blown and leaking into the intake like crazy. Think I'm lucky it didn't hydrolock on me. I found stuff about PMM but not much about their oil cooler.

Seems that a past post talked about having larger passages through the cooler. Thus, it doesn't reduce the temp of oil as well as the OEM oil cooler does.
I'll see if I can find that post.

Oops, I might have been thinking about another one. IPR research had a new oil cooler that did that. Not sure where PMM has gotten theirs from.
Did their packaging or info call it a "high flow" oil cooler per chance?
